My implementation seems to be running almost as fast as raw pointers, which I think is a good sign. What worries me here is why Boost is running slower. Have I missed something in my implementation that is important and I might get into trouble for later? So the idea behind this is ma...

The solution to the above problem is Smart Pointers. Smart pointers automatically handle many of these problems. They are basically an object which behave like pointers i.e. wrap a bare pointer but provides extra functionality. So we should use these in place of bare pointers. Now, let us u...
The reason this cannot be done in Java is that we have no guarantee over when the object will be destroyed, so cannot guarantee when a resource such as file will be freed. Onto smart pointers - a lot of the time, we just create objects on the stack. For instance (and stealing an ex...
To be smarter than regular pointers, smart pointers need to do things that regular pointers don't. What could these things be? Probably the most common bugs in C++ (and C) are related to pointers and memory management: dangling pointers, memory leaks, allocation failures and other joys. Havi...
Smart pointers, as in Listing One(a). 2. Making your own implementation, such as Listing One(b). The good thing about smart pointers is that they are... T Ottosen - 《Dr Dobbs Journal》 被引量: 0发表: 2005年 加载更多来源期刊 The C Users Journal archive 1995-12-01 站内活动 ...

For instance, a pointer might represent: the return value of an address-of operation on a local variable; a position in array and a dynamically allocated object. The purpose of unsmart pointers is to assign separate types to pointers based on their behavior. The implementation proposed by the...
Function arguments should be simple: onlyint,double,char *,void *are supported. Usechar *for NUL-terminated C strings,void *for any other pointers. In order to import more complex functions (e.g. the ones that use structures as arguments), write wrappers. ...
